1.7 Area of use

NGC-20-C(L)-E controllers are used for temperature control and temperature limiting of electrical heaters in industrial and potentially

explosive atmospheres. The NGC-20-CL-E consists of a temperature controller and an additional safety temperature limiter.

NGC-20-C(L)-E units are approved for use in hazardous area Zone 1 and Zone 2 (Gas) and Zone 21 and Zone 22 (Dust). Where needed

the temperature sensor of the unit can be placed in Zone 0 (Zone 20) However, the control unit itself is not approved for being installed

in Zone 0 (Zone 20).

1.8 Safety instructions

During operation, do not leave this Instruction Manual or other objects inside the enclosure. Use the temperature controller and limiter

only for its intended purpose and operate it only in clean, undamaged condition. In the event of incorrect assembly, the requirements of

IP66 as specied by IEC 60529:2001 are no longer met. Do not make any modications to the temperature controller and limiter that are

not expressly mentioned in this Instruction Manual.

Whenever work is done on the temperature controller and limiter, be sure to observe the national safety and accident prevention

regulations and the safety instructions given in this Instruction Manual.

1.9 Conformity with standards

NGC-20-C(L)-E units meet the requirements of the following Hazardous area- and functional safety standards and are developed,

manufactured and tested in accordance with state-of-the-art engineering practice.
